How to Reduce 4x in Iracing

Learn how to reduce 4x in iRacing with a calm step-by-step guide for iRacing beginners and those new to iRacing. One quick fix, a drill, and practical iRacing tips.

If you’re new to iRacing and your framerate stutters or the image looks oddly soft, that tiny “4x” label in the graphics menu is probably the culprit — and it’s easy to change. This guide explains what that “4x” usually means, why it matters to iRacing beginners, and a calm, clear path to fix it.

Quick Answer — how to reduce 4x in iracing

Most of the time “4x” refers to 4x anti-aliasing (MSAA) in iRacing’s graphics settings. To reduce it: open Options → Graphics → Anti-Aliasing and change 4x to 2x or Off. Restart iRacing, test FPS, and tweak other graphics if needed.

Why this matters for beginners

If you’re new to iRacing, figuring out how iRacing works visually can be intimidating. Anti-aliasing smooths jagged edges but costs GPU power. iRacing beginners often keep 4x because it “looks better,” then wonder why the sim lags. Reducing 4x improves frame rates and responsiveness — which helps your lap times and keeps racing fun.

Common mistakes (and how to fix them)

  • Mistake: Changing resolution first. Fix: Lower AA before dropping resolution — AA often costs more performance per visual gain.
  • Mistake: Using GPU control panel overrides and the in-game setting together. Fix: Use the in-game AA or disable overrides to avoid conflicts.
  • Mistake: Assuming 4x = required. Fix: Try 2x or Off — many cars look fine and you’ll gain smoothness.

Simple step-by-step guide

  1. Open iRacing and go to Options → Graphics.
  2. Find Anti-Aliasing (might say MSAA or AA) — it will likely be set to 4x.
  3. Change 4x to 2x or Off, then Apply.
  4. Restart iRacing for clean results.
  5. Test on-track for input lag and FPS (use the built-in FPS counter or a third-party tool).

Small practice drill

Load a practice session at a busy track (like Silverstone) and run 3 timed laps first with 4x, then change to 2x or Off and run 3 more laps. Note FPS, perceived smoothness, and whether distant objects look distracting. This quick A/B test shows the real impact.

Quick pro tips

  • Use the in-game FPS counter (or Steam overlay) to compare settings.
  • If you have an NVIDIA/AMD control panel override, set it to “Application-controlled” then change iRacing’s AA.
  • Lower “Render Scaling” or shadows before lowering resolution for better visual/CPU cost balance.
  • If you race with wheel input, prioritize stable FPS — consistent frame time beats prettier graphics.
  • Keep drivers’ aids and post-processing tweaks simple for better clarity.

When to ask for help

If changing AA doesn’t change FPS, or the option is greyed out, it could be a driver or GPU issue — ask on iRacing Discord communities or official forums with your GPU model and iRacing version. Those communities are friendly to players new to iRacing and great for quick troubleshooting.

FAQs

Q: What exactly is “4x”?
A: It usually means 4x multi-sample anti-aliasing (MSAA) — a graphics smoothing option.

Q: Will turning 4x off ruin the visuals?
A: Not usually. You may see slightly sharper jagged edges, but the sim will be much smoother, which helps driving.

Q: Where is the setting?
A: Options → Graphics → Anti-Aliasing (in iRacing). If disabled, check your GPU control panel.

Q: Still lagging after changing it — now what?
A: Update GPU drivers, close background apps, lower shadows/render scaling, or ask in iRacing Discord with system specs.

Final Takeaways

Reducing 4x in iRacing is one of the easiest, highest-impact tweaks for new players. Try 2x or Off, run the short drill above, and choose stable FPS over tiny visual gains. Next session: change the setting, restart, and notice how much smoother racing feels.
